Summer 2023 Note: For Summer Precalculus (Math 1A & 1B) and Calculus Courses (Math 2A, 2B, 5A, & 5B), no placement test is needed to enroll in these courses. Students can register directly for the course that is best for them during Summer Sessions 1 or 2. These courses are offered online during both summer sessions.
Notes
There are three ways by which the Department of Mathematics places students into the appropriate calculus or precalculus courses at UCI:

The AP Calculus AB or AP Calculus BC test

The Math SAT or the Math ACT (while these exams are no longer used at UCI in the application process the Department of Mathematics still uses them to guide student enrollment)

The ALEKS Placement test. This exam is provided by ALEKS Corporation. Your purchase includes access to ALEKS online educational modules for Preparation for Calculus for six months and two attempts on the placement exam.
Enrollment Guide

If you took the AP Calculus AB or AP Calculus BC test and:

you scored a 4 or a 5 on the AP Calculus BC test, then you should enroll in Math 2D (Multivariable Calculus I). (If you have trouble enrolling into Math 2D, and never released AP scores to UCI, then please upload a copy of your AP test results here.)

you scored a 4 or a 5 on the AP Calculus AB test OR a 3 on the AP Calculus BC test, then you should enroll in Math 2B (Single Variable Calculus II). (If you have trouble enrolling into Math 2B, and never released AP scores to UCI, then please upload a copy of your AP test results here.)

you scored a 3 on the AP Calculus AB test, then you should enroll in Math 2A (Single Variable Calculus I). (If you have trouble enrolling into Math 2A, and never released AP scores to UCI, then please upload a copy of your AP test results here.)

If you took the SAT or the ACT and:

you scored a 650 or better on the Math SAT OR a 29 or better on the Math ACT, then you should enroll in Math 2A (Single Variable Calculus I) or Math 5A (Calculus for Life Sciences). (If you have trouble enrolling into Math 2A/5A, and never provided SAT or ACT scores to UCI, then please upload a copy of your test results here.)

If neither 1) nor 2) apply to you and you took the ALEKS placement test and:

you scored 80 or better, then you should enroll in Math 2A (Single Variable Calculus I) or Math 5A (Calculus for Life Sciences). (If you have trouble enrolling into Math 2A or Math 5A, email mathinfo@math.uci.edu and include a copy of your test score.).

your score was less than 80 but 61 or greater, then you should enroll in Math 1B (PreCalculus II).

your score was less than 61 but was 46 or greater, then you should enroll in Math 1A (PreCalculus I).

During Summer 2023 only, the ALEKS placement is waived and students can place themselves in Math 1A, 1B, 2A, 2B, 5A, or 5B.

If none of 1), 2), and 3) apply to you, then

It is highly recommended that you take the ALEKS placement test and then refer back to the guidelines in 3). Instructions on taking the ALEKS placement test and accompanying precalculus education material can be found here.
